PHOENIX — Thursday was the hottest day of the year for Phoenix as we hit 117 degrees. This was also the peak of our current heat wave but we are still in-store for one more day of extreme heat.

Due to the dangerous conditions, ABC15 Weather Action Days remain in effect through the end of the week. This is a critical reminder to take steps to stay safe during this stretch of extreme heat.

Make sure to stay hydrated, limit time outdoors during the hottest part of the day between 11 a.m. and 6 p.m., and wear light-colored, breathable clothing. If you need to be outside, take frequent breaks in the shade or indoors when possible, and reapply sunscreen throughout the day.

Never leave children or pets in the car, and ensure pets have a cool and comfortable place to stay inside during the heat of the day.

Phoenix is forecast to hit 116 degrees today. If we reach that mark, it would be our first day above 115 degrees this year, coming early compared to the typical first 115-degree day, which usually happens around July 8.

Extreme Heat Warnings remain in effect through Friday for the Valley, the Grand Canyon below 4,000 feet, and southern Arizona.

Some relief may arrive this weekend as a stronger weather system moves in from the Pacific Northwest. This could help push temperatures closer to, or even slightly below, normal by early next week.

That shift, however, comes with fire concerns. Gusty winds, low humidity, and lingering heat could increase fire danger across the state.

Red Flag Warnings are in place for Mohave County through Friday evening, and for northeastern Arizona on Friday and Saturday as hot, dry, and windy conditions take hold.

Wind Advisories are also posted for Northeast Arizona on Friday and Northwest Arizona on Saturday with wind gusts expected to exceed 35-45 mph.

The monsoon season officially began on Sunday, June 15, but so far, dry southwest winds are keeping moisture and storms out of Arizona. That may start to change this weekend as a bit of monsoon moisture moves into southeast Arizona, bringing a chance for isolated showers and storms early next week in Southeast Arizona.

The Valley forecast remains dry for now, but we’ll be watching closely and will keep you updated.
